Air leakage is an essential factor contributing to overall building performance. It plays a major role in determining energy consumption harsh climates, particularly residential buildings, as it represents significant component of the envelope-induced thermal load. In centrally air-conditioned houses, HVAC system can substantially alter pressure distribution across exterior envelope, reforming ...

In the title compound C(17)H(25)NO(2), the piperidin-2-one ring adopts an envelope conformation with the C atom in the 5-position as the flap. The crystal packing is stabilized by inter-molecular O-H⋯O hydrogen bonds, building a infinite chain along the b-axis direction. C-H⋯π inter-actions further stabilize the crystal packing.

We define filtrations by affinoid groups, in the Berkovich analytification of a connected reductive group, related to Moy–Prasad filtrations. They are parametrized cone, whose basis is Bruhat–Tits building and vertex neutral element, via notions Shilov boundary holomorphically convex envelope.

In the racemic title compound, C(14)H(11)N(3)O(3), the pyrimidine ring has an envelope conformation with the puckering parameters Q = 0.3338 (17) Å, Θ = 60.1 (3) and ϕ = 290.4 (3)°. The two N-H groups form hydrogen bonds with symmetry-related mol-ecules, building a two-dimensional network parallel to the (10) plane.

In residential buildings, air infiltration impacts energy, indoor quality, and thermal comfort considerably. While in buildings has been the focus of many studies, most published field-testing results pertain to developed countries, with little or no data on developing nations. This paper presents one first field investigations into envelope hot-arid climatic area Egypt. To analyze permeability...

The critical aims of glass envelope design and development must be to enable measures upon glass buildings to prevent uncontrolled heating of the building surfaces, increase emissivity and the impacts of this heat conduction into the building interior spaces. Current glass envelopes depend upon hybrid facades, double skin glass facades; solar shading; passive solar energy systems (transparent i...
